The Chicagopcb SI simulation team has 15+ years of experience in DDR4/DDR3/ DDR2 parallel bus and high speed serial bus simulation such as PCIESATASASSFP+ and 10G-KR. We provide suggestions to design the proper topology, select the best termination and driver, and optimize the whole channel to get the lowest loss and best eye open. We also have DDR4 and 25Gbps+ signal design and simulation capabilities.
